New York State Police are investigating the cause of a tractor trailer roll-over crash on Interstate 81 in Kirkwood.

Authorities say the northbound truck loaded with potatoes rolled over in a construction zone shortly before 11 p.m. April 15th, leaving the driver with minor injuries.

The traffic pattern in the construction area had to be shifted in the overnight hours then diverted completely off the highway for a couple hours in the morning so the truck could be removed.
